To a/ZZ .wh/0m it may concern:

Be it known that I; WILLIAM J. BAULIEU, a citizen of the United States,and a resident of Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inAcetylene- Gas Machines, of which the following is a specification.

My invention relates to gas-machines of the acetylene type and comprisesimprovements on several of my prior inventions and novel features whichare equally applicable to other styles of machines.

It is the object of myinvention to improve the efficiency ofgas-machines in several important particulars, the first of which is toprovide a more sensitive mechanism for governing the supply of water tothe carbid-generators; second, to improve on the means of distributingthe gas in the wash and for otherwise purifying the gas, and finally tosimplify and further improve the construction of machines wherebyalarger. percentage and improved quality of gas are obtained from thecarbid with comparatively little attention by the user.

With the above object in View -myinvention resides and consists Y inthefnovel construction and combination of parts set forth in thevaccompanying three sheets of drawings, forming a part of thisspeciticatio'rn and upon which similar characters of 'reference denotelike or corresponding parts throughout the several gures, and of which-Figure l shows a plan view of my complete machine. Fig. 2 shows aninverted sectional Fig.3 shows a central vertically-longitudinal sectiontaken on line 3 3 of Fig. l. Fig. 4 shows a central verticalcross-section on line t 4 of Fig. l and illustrates the pipe connectionsof said generators and the relation of one with the other. Fig. 5 is adetail view of the top portion of a bell -used in my machine and showingtherein a modification `which will later be again referred to.

The construction of my machine, as will be apparent, embodies astorage-gas reservoir which is fed from an intermediate reservoircontaining a purifier and through which the gas passes from the severalgenerators, of which I have illustrated three in the drawings. It willbe apparent, however, that a greater number of these generators may beemployed, in which case they would be connected one with the other, asis the case in my present construction.

Referring in detail by letters of reference to the construction of mymachine, A indicates a base for the tank B of the storage-reservoir, andC the bell thereof.

D indicates the Wash-tank, which 'also serves as a support for the tankE of the intermediate reservoir, of which F is the bell. The tanks Gl ofthe several generato rs are also supportedupon the tank D, as will beapparent from the several figures of the drawings.

Since the several generators are alike in construction, I will ilse thesame reference characters to indicate like parts through each of them.

\ H indicates a carbid-pot, which may be in the form of a bucket andprovided with a suitable handle whereby it can be removed from time totime for-recharging. This pot,

' as Will be apparent, is set down in the Water of the tank G. SaidWater is increased from pipe J until it reaches the level of theperforations I of the pot, through which it is fed onto the carbid,whereby gas is generated. Said Water referred to Within the tank G isincreased from time to time from the supply in the main storage-tankthrough the following connections: A pipe J projects up within the tankG and is connected (see Figs. 2, 8, ande) by a horizontal pipe K withthe adjoining generator, whereby the Water may be fed from one generatorto another as they become flooded. Within one of these horizontal pipesK, I locate a three-Way valve L, the handle L of which projects upthrough the covering of the wash-tank, as will be apparent. `Said valveis connected by a valve M, which regulates-the feed-water to thegenerators and-which is connected to a pipe N from the water-supply ofthe main storage-tank. The stem of the valve M is inclosed within a pipeO and is provided at its upper end with a lever P and connection Q withthe topV of the bell of the intermediate reservoir. It loo will thus beapparent 'that when said bell rises with an excessive accumulation ofgas the valve in question will immediately be` closed with considerableforce and so held until the pressure from the bell F is released.

Referring again to the water connections ofthe generators, it will beseen that there are two pipes of equal heights for each generator, (seeFig. 4,) one of them constituting an inlet and the other an out-let andeach being a part of a U-shaped connection. The water is fed through thevalves L and M before mentioned to one of the adjoining generators andthen to the successive generators in their respective orders as theybecome flooded.

The inclosure for the generators comprises a bell R, which is providedwith a cylindrical extension-top S, having a anged cover to rest uponthe rim of the tank. Said cylinder' only serves as an empty extension,whereby the bell may nish even with the top of the generator. Aninternal barrelshaped inclosure T is located in the cylinder and formsan extension for the bell ot the generator and through which the gaspasses to the pipe U for delivery to the wash. rPhe tanks of the severalgenerators may be provided with cocks g, whereby the water can be drawnoff from time to time should occasion require. The iianges of the coversof said generators are also provided with locking mechanism which, asVwill be seen, comprises simply a notch 71 under which an extension t'of the cover is turned.

The lowelI end of the pipe U is provided with a distributer in the formof a perforated disk V, having an annular depending flange. The purposeof this distributer is to afford a cheap and desirable construction forbreak ing up or separating the volume of gas as it flows into the water.The perforations in question are preferably very tine to insure a smallstream of gas passing through each. From this distributer the gas iswashed through the water of the tank and finds its way up through theinternal conical-shaped wall W of the tank E and emerges throughperforations d at the top and into the bell F ot' the intermediatereservoir, where said gas is again exposed to the surface of the watercontained in said reservoir. The gas next passes through the purifier X,which consists of a cylindrical body having a perforated to p andbottom, the intermediate chamber being iilled with a suitable packing Z,such as cotton or other like material. From the above it will beapparent that the gas en ters the perforated cover and passes throughthe packing and out through the bottom. From said purifier the gas ispassed down through a pipe a into a horizontal pipe b and u p throughthe main pipe c forservice. Within the horizontal pipe Z) I locate abranch pipe j, through which the excessive supply of gas is delivered upinto the storage-reservoir and whereby the gas from said tank may inturn be deliveredto the mai n pipe for service. I also preferablyprovide said pipe h with a drip f, as will be apparent in Figs. 2 and 3,which permits of the escape of any Huid which may accumulate therein.

Within the bell of the main storage-tank I provide a pocket or a seriesof pockets Y, which in a measure act as a weight and afford at a desiredtime a resistance to the upward movement of the bell, whereby themovement of the bell of the intermediate reservoir is controlled by themovement of the other.

The foregoing will be best understood when explained, as follows: Whenthe valve M is open, the water (iows from the storage-tank into thecarbid-generator, from whence the gas escapes through the wash and upinto the bell F of the intermediate reservoir. rlhis reservoir beingweighted, as at e, a resistance is afforded, and the gas flows on to theadjoining storage-reservoir, causing its bell to rise, whereby thelatter draws the pockets up through the water until the top level isreached, when the extra weight of said pockets and the fluid containedtherein aitords a marked resistance to the movement and backs the gasinto the bell of the first reservoir, causing the same to rise, wherebythe valve M is quickly and firmly held by the weights in question andthe flow for service would likewise be more desirable.

With a weighted bell and connections as herein described the relativeposition of the two bells when in use is that the larger one standshigher than the smaller one until the pockets begin to emerge from thewater and that throughout the operation of the machine the pockets ofthe large bell play to and fro in and out of the water in accordancewith the quantities of gas contained in the bells.

In the modification shown in Fig. 5 it will be seen that I haveillustrated an annular pocket instead of a series, as indicated in theother figures. This is obviously cheaper to construct and fully aspracticable in every particular. I therefore do not wish to be limitedto the construction shown in my preferred form. In fact, I do not wishto be limited to fluid-pockets of any kind, since aconstruction ofweights may be provided whereby at a given time the force of the samemay be applied to the bell to retard its movement and to back the gasinto the bell of the intermediate reservoir for operating a valve tocontrol the supply of water to the generators proper.

The wash-tank D is preferably closed, so as to prevent the escape ofwater therefrom, since I find in practice that it is particularlydesirable to retain the same water for wash ing purposes as long aspossible, as said water becomes charged with substances from the gas andbetter adapts it for cleansing and with less loss of gas from passagetherethrough. I also find that after using the water for a time with theconstruction as herein IIO i 670,657 v f '-153 illustrated it ispossible when covering the generators to i'nclose a quantity of airWithin the bell and force said air down through the pipe O and throughthe Wash, taking with it more or less of the gases therefrom in amannerto further improve the quality and increase the quantity.

The operation of my machine is as follows: The Water for the generatoris taken vin through pipe N and the quantity thereof is governed by thevalve M, which latter in turn is controlled by the operation of the bellE of the intermediate reservoir. The Water passes through valve M and isdefiected by valve L to the right or left in one of the adjoininggenerators. The gas made by this infiow of water escapes through pipe Uand its distributer into the water, from which it escapes and passes upinto the conical wall and emerges through the perforations under thebell of the intermediate reservoir. From thisV reservoir the gas passesthrough the purifier to the large reservoir, when the gas acts to raisethe bell. As the pockets of this bell emerge from the Water a Weightedresistance is offered to the movement of the bell, and consequently the.gas is backed into the intermediate reservoir, causing its bell to rise,which immediately acts on the valve M and cuts off the supply of Water.By reason of the connecting U-shaped pipes J and K the generators arepermitted to overfiow one into the other, thus successively exhaustingthe carbid thereof.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, iS
